L432 AC Current Loggers

The Simple Logger II Model L432 is a two channel DC data logger. The choice of data storage modes and storage rates allows the operator to effortlessly configure the logger to optimize memory usage to the application at hand. Extended Recording Mode (XRM) and delayed start time are just two of the many application friendly features.

The Simple Logger II Model L432 records DC voltage at user selectable rates from 8 per second to 1 per day. Voltages can be measured up to 10V with 0.01V resolution in user selectable ranges of 0-100mV, 0-1V and 0-10VDC.

The main advantage of the logger is its ability to perform a variety of recording tasks with easy and intuitive setup from a computer using DataView software.

Analog information on the input is sampled and converted to a digital signal. This digital signal is processed and stored along with scale and time information. An optically isolated Universal Serial Bus (USB) port provides for the transfer of data from the instrument’s internal memory to the computer for analysis.

DataView Graphing & Analysis Software

The DataView software provides a convenient way to configure and control logging from your computer. Through the use of clear and easy-to-use tabbed dialog boxes, all Simple Logger II functions can be configured and tests can be initiated. Results can be displayed in real time and stored in your PC or the logger. Standard or custom reports may be printed along with the operator’s comments and analysis.

3 Recording Modes

Start/Stop Mode
In this mode the operator selects a storage rate from predefined values from 8 per second to 1 every day, then selects a start and stop time. Data is recorded at this rate until the memory is filled or the end recording time and date is reached. The logger then stops recording and goes into standby mode retaining the recorded date.

First In First Out Mode (FIFO)
The operator makes the data storage and recording length selections as described above. If the memory fills before the end date and time occurs, the logger will discard the oldest stored data point and add a new one. This process will continue until the end recording date and time is reached.

Extended Time Recording Mode (XRM)
This unique recording mechanism provides for continuous recording over a longer period of time without the need for the operator's selection or adjustments. The operator selects a starting storage range from predefined values from 8 per second to 1 every day and a recording length. The logger will store data at the rate selected until the memory is filled. The logger will then discard every other stored sample beyond the first one, freeing up half the memory for continuous recording. New samples will be stored at half the previous storage rate, matching the interval with the remaining stored data. This process will repeat each time the memory fills until the operator stops the recording manually, the end recording date and time is reached or the battery runs down.
